512 Mbit parallel NOR, 24-FBGA footprint
The S26KL512SDABHB020 is a 512 Mbit parallel NOR flash from Infineon's Automotive AEC-Q100 HyperFlash™ KL family, organized as 64M x 8 bits. The 24-VBGA package (6x8 mm body, 24-FBGA) demands a 4-layer board for fan-out of the fine-pitch BGA.
Access time and clock rate — the read-performance ceiling
At 100 MHz, the parallel interface delivers sustained read throughput limited by the 96 ns random access time. The first-word latency is 96 ns; subsequent words in a page burst follow at the clock rate — the effective bandwidth depends on burst length and the controller's prefetch policy.
